This was my first large putter grip experiment. The grip shape is a flattened large oval. The premise is that you put both hands at the same level with you thumbs together to get you to make a smoother stroke without one hand dominating. I never got to like that technique though. I do like the larger grips, and this is a good one. The only thing is that with age the grip seemed to get a little slick/smoothed out. It was way more tacky when it was new. I have since gone to the superstroke grip that is more of a large round grip with a flat section on it. This two thumb is a good price at Golfsmith.
